Innovation is a popular theme in society as well as in public administration. This essay focuses on innovations that take place within the realm of the public sector. How can these innovations be developed and what do we know about their adoption and diffusion? Is it possible to steer these innovations and if so, how can it be done? Based on analyses of recent scientific insights, Bekkers, Edelenbos and Steijn (2011) plea for an incremental adaptive evolutionary public innovation strategy. Within the framework of such a strategy, innovation has to be directed towards increasing the connective capacity within government. Also, the specific, political character of the public sector as the context of innovation has to be acknowledged. Furthermore, it is also important to find a balance between the logic of consequentiality and the logic of appropriateness. Based on dissertations by Huijboom (2010), Korteland (2011) and Oosterbaan (2012) the meaning of this evolutionary strategy for public sector organizations is explored.

Currently, Dutch cities are facing persistent societal problems as well as changing circumstances, due to the financial crisis and changing national policies. This special issue seeks to take analysis beyond a sense of mere crisis and investigates contemporary urban initiatives in order to discern what innovative modes of governance they offer.
